摘要

The blast-wave flows both outside and inside a power house of a nuclear-power generating station, from an accidental explosion of an explosive like TNT or its equivalent during transportation past the power house by a train, are studied numerically and assessed with an appropriate model. Detailed descriptions of both the prediction model and numerical method of solution are given, as well as an interpretation of numerical results. The blast-wave flow into the power house through blow-out panels in the front wall is investigated, including the resulting flow inside the power house that travels through the turbine hall, through the turbine auxiliary bay, over the reactivity deck, through the reactor building, and, in some cases, down through a hoistway to three small rooms on the next lower level. Breaking blow-out panels in the rear wall of the power house and their effects on the internal blast-wave flow is also investigated. Two different flow paths are considered, one through an upper level of the power house and another through a lower level. Finally, the blast-wave flow over the outside of the power house is studied, with an approximate model, so that the pressure differences from the blast wave between the inside and outside of the roof, side walls, front wall, and rear wall can be determined and the resultant blast-wave loading on the building walls thereby obtained.
